About
The Institut fuer Energieuebertragung und Hochspannungstechnik (IEH) at the University of Stuttgart, led by Prof. Dr.-Ing. Stefan Tenbohlen, offers its research facilities on the Vaihingen campus as contract testing services, and its centre of gravity is high-voltage engineering rather than EMC. The high-voltage hall performs AC withstand testing with simultaneous partial discharge measurement to IEC 60270, lightning and switching impulse voltage testing, capacitance and dissipation factor (tan delta) measurement, relative permittivity and dielectric loss characterisation of liquid and solid insulation, and breakdown and withstand testing - supported by dissolved gas-in-oil analysis with headspace sampling, insulation moisture determination and high-speed optical imaging for tracking particles in insulating fluid, a combination used for transformer condition assessment and fault diagnosis. Alongside that sits a power network group measuring supply quality against EN 50160 and testing controllers and protection devices in real-time hardware-in-the-loop environments. The EMC offering is deliberately scoped as pre-compliance: radiated and conducted emission and immunity measurement to the DIN EN 61000 series and electrostatic discharge resilience testing for CE marking purposes, backed by three-dimensional electromagnetic field simulation, which lets a coupling or emission mechanism be reproduced numerically as well as measured. As a university institute it holds no ISO/IEC 17025 accreditation and is recorded here without one; work is contracted as research and development service rather than accredited certification. Specialisations are power transformers and insulation diagnostics, grid and power quality measurement, protection and control device testing, and EMC simulation-led investigation.
